A graded negative refraction-index phononic crystals plate lens for focusing A0 mode Lamb wave and energy harvesting
In this paper, a method of rotating scatterers was used to design a graded negative refraction index phononic crystal (GNRI PC) plate lens. The present plate lens contains the periodic perforated three-fan holes as the scatterers in the epoxy plate matrix. For a given rotation angle of the scatterer...
